I am currently going to physical therapy for pain in my left upper arm. I quickly built up muscle, but the pain is still there and seems to be nerve rather than injury related- the new normal is that I can't fasten my bra or pull over a top without sharp pain. What is relevant to your situation is that I seem to have a milder "shadow" type of pain in my right upper arm. Not as bad, but similar.
I think with PN there is an underlying pull toward making everything more or less bilateral.
Hoping to hear from others on this idea.
